Tic Stepper Motor Controllers, QTR Reflectance Sensors, Pololu Wheels & Tracks, Arduino Shields, and Raspberry Pi Expansion Boards

The Tic offers simple control of bipolar stepper motors directly from a variety of interfaces, including USB, TTL serial, I²C, hobby radio control (RC), analog voltage (potentiometer), and quadrature encoder signals.

These sensors use pairs of infrared LEDs and phototransistors to measure how much of the emitted IR light is being reflected from a nearby surface. They are great for edge detection and line following.

Our selection of plastic wheels and track systems press-fit onto the 3mm D shafts of our micro and 15.5D metal gearmotors to make a nice drive solution for small robots.

Shields are expansion boards that conveniently add peripheral electronics to Arduinos.

Augment your Raspberry Pi project with motor drivers, advanced power regulation, and more.
